This coming weekend includes a marquee event in the fight against opioid addiction. Saturday, October 27 is the Drug Enforcement Agency’s (DEA) National Prescription Drug Take Back Day—dedicated to dumping unused, unneeded, and (to others) potentially harmful prescription medications that still may be lying around the house.

This year, though, tech giant Google is expanding its involvement in the effort. In fact, Google Maps will post 5,800 locations where people can dispose of powerful painkillers and other prescription drugs in a (relatively) new tool.

The product was first released back in April, and Google says that 50,000 Americans used the locator service on its very first day. “Every day 134 people die from opiate related overdoses—and misuse of prescription painkillers is a large contributor to this crisis,” says the company in a statement. “Thankfully, there is something we can do. One way that you can help reduce the potential misuse of drugs is to properly dispose of expired or unused medications.” The firm points out that expired medicines left lying around could also have environmental effects if they aren’t thrown out properly.

The National Take Back Day hours last between 10 am and 2 pm on Saturday. Furthermore, Google announced a partnership earlier this week with Walgreens, which has numerous drug disposal sites, to add such locations to Maps year-round.
